How to Call Vietnam from the US: A Complete Guide
Calling internationally can seem daunting, but with a little preparation, connecting with family, friends, or business partners in Vietnam from the United States is straightforward. This comprehensive guide will walk you through everything you need to know, from understanding time differences and dialing codes to exploring various calling options and finding the most cost-effective solutions.
## Understanding the Basics: Time Difference, Exit Codes, and Country Codes
Before you even think about dialing, it’s crucial to understand the fundamental elements involved in international calling. These include the time difference, the US exit code, and Vietnam’s country code.
* **Time Difference:** Vietnam operates on Vietnam Standard Time (VST), which is GMT+7. This means Vietnam is 12 to 15 hours ahead of the United States, depending on the time of year and whether Daylight Saving Time is in effect in the US. Specifically:
* When the US is on Standard Time (roughly November to March), Vietnam is 13 hours ahead of Eastern Time (ET), 14 hours ahead of Central Time (CT), 15 hours ahead of Mountain Time (MT), and 16 hours ahead of Pacific Time (PT).
* When the US is on Daylight Saving Time (roughly March to November), Vietnam is 12 hours ahead of Eastern Time (ET), 13 hours ahead of Central Time (CT), 14 hours ahead of Mountain Time (MT), and 15 hours ahead of Pacific Time (PT).
Always double-check the current time in both locations to avoid calling at inconvenient hours. Online time zone converters are readily available for this purpose.
* **US Exit Code:** The exit code, also known as the international access code, is the sequence of digits you dial from the US to indicate that you’re making an international call. In the United States, the exit code is **011**.
* **Vietnam Country Code:** Each country has a unique country code, and Vietnam’s country code is **84**.
## Step-by-Step Guide to Calling Vietnam
Now that you understand the basic codes and time differences, let’s break down the exact steps to call Vietnam from the US:
1. **Dial the US Exit Code:** Begin by dialing **011**.
2. **Dial Vietnam’s Country Code:** Next, dial **84**.
3. **Dial the Area Code:** Vietnam has area codes for different regions and cities. This is typically a two- or three-digit number. *You must know the correct area code for the specific location you are calling.* Common area codes include:
* **Hanoi:** 24
* **Ho Chi Minh City (Saigon):** 28
* **Da Nang:** 236
* **Hai Phong:** 225
4. **Dial the Local Phone Number:** Finally, dial the local phone number of the person or business you’re trying to reach. This is typically a seven- or eight-digit number.
**Putting it all together, the complete dialing format looks like this:**
**011 + 84 + Area Code + Local Phone Number**
**Example:** To call a number in Hanoi (area code 24) with the local number 12345678, you would dial:
**011 84 24 12345678**
